System and Method for Moving a Drilling Rig

Abstract

An improved system and method for moving a drilling rig is described herein. In one embodiment, the system can comprise a lift cylinder maneuverable in a longitudinal direction, a casing having a portion of lift cylinder attached at the center of the casing, and an anchor where a top portion of the anchor is connected to the bottom portion of the lift cylinder. The casing can be mateable at the bottom portion of a drilling rig. The walking system can further comprise a pair of traverse cylinders mounted on opposite sides of the anchor and a skid pad, on which a portion of the traverse cylinder is connected. The traverse cylinder can be maneuverable in a lateral direction. The skid pad can be connected to the bottom portion of the mounting plate. Furthermore, the skid pad can be capable of supporting the weight of the drilling rig.

1 . An improved system for moving a drilling rig comprising
 a lift cylinder maneuverable in a vertical direction;   a casing, a portion of said lift cylinder attached at the center of said casing, further wherein said casing is mateable at the bottom portion of a drilling rig;   an anchor, a top portion of said anchor connected at the bottom portion of said lift cylinder;   one or more traverse cylinders mounted on the opposite sides of said anchor; said traverse cylinders maneuverable in horizontal direction; and   a skid pad, a portion of said lift cylinders connected to said skid pad, said skid pad connected to a bottom portion of said anchor, further wherein said skid pad is capable of supporting weight of said drilling rig.   
     
     
         2 . The system of  claim 1 , wherein said lift cylinder is a single acting cylinder. 
     
     
         3 . The system of  claim 2 , wherein said single acting cylinder is maneuverable in one direction. 
     
     
         4 . The system of  claim 1 , wherein said lift cylinder is a double acting cylinder. 
     
     
         5 . The system of  claim 4 , wherein said double acting cylinder is maneuverable in two opposite directions. 
     
     
         6 . The system of  claim 1 , wherein said lift cylinder is rotatable. 
     
     
         7 . The system of  claim 1 , wherein said skid pad uses a track and a guide method. 
     
     
         8 . The system of  claim 7 , wherein said guide is mountable to said anchor. 
     
     
         9 . The system of  claim 8 , wherein said anchor is capable of sliding within said guide. 
     
     
         10 . The system of  claim 9 , wherein said anchor comprises a plurality of rollers. 
     
     
         11 . An improved method for moving a drilling rig comprising
 expanding a lift cylinder, said lift cylinder is capable of lifting a drilling rig upwards such that a skid pad presses against the ground;   horizontally expanding a traverse cylinder, further wherein said drilling rig is directed laterally;   
     
     
         12 . The method of  claim 10  further comprising
 extracting said lift cylinder, wherein said drilling rig rests against the ground and said skid pad is slightly raised above the ground; 
 horizontally extracting said traverse cylinder, wherein said drilling rig is maneuverable laterally; 
 
     
     
         13 . The method of  claim 11  further comprising rotating said lift cylinder such that said skid pad is rotated towards another direction.
